To all whom it may concern: l

Be it known that I, WILLIAM E; HASKELL,

a citizen of the United States, residing at Brattleboro, in the countyof Windham and trolling the same is called the Oboe stop;

and the object of the present improvement is to secure thischaracteristic and peculiar tone by the construction andvoicing of thepipe without the employment of any vibratr mg reed or other moving part.

The improvements are illustrated in the accon; inying drawings in whichaa Figure 1, is a front view of a metallic organ pipe embodying theimprovements.

1s a vertical longitudinal section. Fig. 3, is as an enlarged verticallongitudinal section of the pipe in the vicinity of the mouth. Fig .4,isa cross-section'in the plane indicated by the line 4: 4 in Fig.3. Fig.5, is a horizontal section in the lane indicated by the line 5-5 in Fig.3. ig. 6, is a detail view of the lower lip and. the languid. p

A,'is the body of the ipe; B, is its foot, having toe a, with port, C,is the mouth, having upper lip'c, and lower lip 02; D, is the languid,

the windway e; E, is a cup below the mouth,

i I and between the front of which and the front- ,of the foot is athroat f; F, is a roller or draft bridge, infront of the lower portionof the mouth and mounted in vertically extending ears 9, on o ositesides of the mouth; G, is the tuning slit, and. H, is the tuner.

All of: the pipes are made of the usual metal employed in themanufacture of me tallio organ pipes. The smaller pipes of thesto'are'made of'a composition of tin and lea 'and the larger pi es are madeof zinc.

The pipes are. open at t eir to s.

In order that the characteristics of the im proved set of pipes may befully understood, a s ecification will be given of the exactdetai swhich have been followed in the COLIl-r mercial manufacture of the pies,

The front of the pipe is attened at the mouth so that the mouth entendsin a plane fipeci hc aticn of Letters Patent. 'hpplicatioafiloli June24:. 1905- Beriel No. 266.838-

fifths the diameter of the mouth, and the between the two ears 9, g. Thewidth of the maximum diameter of the body of the pipe is six-fifths thediameter at the mouth. The maximum diameter of the body of the pipe issubstantially half way between the mouth and the top of the p1pe. The,body of the pipe gradually diverges from the mouth to the middle, andthen gradually converges from the middle to the top. The cup E, isan imortantfeature of the pipe, and its depth helowthe level of the lower lipis equal to the diameter ofthe body of the pipe at its tops The voicingof the pipe is likewise important.

The up or and lower lips should be bev- I eled as s own to have sharpedges. The roller or draft bridge F, is of wood, and is stationarybetween the ears, being fixed thereto by a pin h. The bridge is circularin crosssection, and its diameter is four-fifths the height of themouth. It is so placed that its center is substantially on a level withthe top of the lower lip, and the distance between it and the upper edgeof the lower lip (at their points of nearest approach) should beaprogrimately one-fifth the diameter of the rx go. I

The bottom of the languidD, is at the same level as the top of the lowerlip. The

front face of the languid is beveled to a sharp edge. The width of thewindway a, between the languid and the lower lip may be varied to aconsiderable extent, do ending u on the volume of tone required an thedept of the nicking on the languid. As a proper average roportion, it.may be stated that the win Way may be about one fortieth as wide as themouth is wide. I

The proportions of the foot B, with its inlet I), may follow ordinaryorgan practice in the construction of metal pipes, having no peculiarityin the present improved stop.

. The lengths of the different pipes in the stop are,' of course,determined by their pitch In the stop which has been commer. ciallyadopted, the CC is the lowest note of an 8 foot register. The heightofthis pipe.

from the level of the lower lip to the extreme top of the pipe is 94.25inches. The diameter at the mouth forthis'pipe is 3.25 inches, that isto say, the length.- of the pipe is I twentyqiine times its diameter atthe stop follow the usual rule governing the pitch of the pipes, that isto say, each pipe is on'e-halfthe heightoi the octave belowpipe, and itentirely open,

The diameters of the pipes do not vary inthe same proportion as do theirheights.

' Taking any given pipe as unity the nine teenth pi e'counting from ithas half itsv diameter, 1 at is to say, if CC is 3.25 inches n diameter,then the nineteenth pipe counting froniit, namely, Fsharp, is 1.625inches in diameter. In this count it is to be noted that both the firstand last pipes are to be recognized. The intermediate pipes vary indiameter in regular geometric progression.

"l. he proportions of each pipe, as based u on the diameter of its mouthas heretofore given, should be'followedinv all pipes of, the sto The proortions which have been given, if exactly to lowed, will reduce a set.of pipes giving the desired qua lty of tone. It is not, however, to beinferred that there can be no departure whatever from these proportions,since they may be varied within limitswithout destroying the tonequality.

The mechanical'construci'ion of they cup E, possesses mechanical noveltyand advanta e. he cup is made of the same metal as t 1e has a closedbottom and eripheral walls all in one piece of metal. T e bot-- tom isfiat,-as is likewise theifront i. The cylindrical portion m, of thecupfits snugly Within the pi e and is conveniently secured in place byso dering. The top of the cup is and the languid D, is convenientlysecured in place by solderin lg to the top of the front wall 'i, of thecup. he cup fits snugly within the pi e so that wind can only passthrough the t roat f, betweemits front Wall and the external body ofthe. pipe at the front.

The cup constitutes the 'bottom' of the pipe-and is below the mouth withits-u per open end at the level-of the bottom 0 the mouth and with itsbottom a distance below the mouth substantially equal to the diameter ofthe top of the pipe. I

I claim as my invention:

1. A metallic organ pi e open atits top and having'a' mouth an having abody the diameter of which at the top is smaller thantlie major diameterin the planeof the mouth, and the diameter of which at the middle islarger than said major diameter at itsmouth.

2. A metallic organ pipe having amouth verges gradually characterized byand charabterized byhaving its top ap roxiinately one-fifth smaller indiameter t anit' is at the major diameter in the plane of the mouth, by.one-fifth arger in diameter than it is at said major diameter at itsmouth, and by diver ing gradually from the mouth to the middland byconverging dletotheto. J3. Ame-ta lic organ ipe characterized by havingits upper and ower -li s beveled at having its middle approximatelygradually from the midtheir outer-faces to a sharp e ge, having alanguid-beveled atits front to a sharp edge,

lower portion of the mouth.'

4. A metallic or an pi' e characterizedby. having a month t e wi th ofwhich is approximately onefifth the" circumference of the pipeat themouth, and the height. of

which. is approximately two-sevenths of its Width, and a draft bridge infront of the lower portion ofthe mouth Whose diameter is sublptantiallyfour-fifths the height of the mout 5. A metallic organ pipe having awindway, a mouth, and a metallic oi 1p open at its top, closed at its.bottom, and fitting closely within the pipe, said cup constituting-thebottom of the pipe and having its open top at said mouth, a throat beingleft between the front of the cup and the front of the pipe for thepassage of wind to the windway.

6. An open top metallic organ pipe having a mouth, a windway, a languid,and admit bridge, and characterized by the following features, namely,(a) its top is ap roxi- 'mately one-fifth smaller in diameter t an it isat its major diameter in the plane of the mouth, its middle isapproximately. one-fifth larger in diameter than it is at said majordiameter at its mouth, it diverges gradually from the mouth to themiddle, and it confrom its middle to it's top;

(b) it hasa cup with itsbottom below the mouth a distancesubstantiallysquat-toithe diameter of its top; (0) the up er and lower.

li s at its mouth are each have ed toe sharp a or go, ari'dits languidis beveled to-a sharp edge; (dithe width of its mouth is approxi matelyone-fifth the circumference of the pipe at the mouth, and the height ofthe mouthis approximately-two-sevenths of its width, i

and (e) its drafti bridge is in front of the:

j lower portion of the mouth and has a diame' tersubstanti'allyfour-fifths the height of the mouth.

In witness whereof, I have hereunto si ned my name in the presence oftwosubsori "pg witnesses.
